Match the following

• Subduction

• process in which two lithospheric plates of different densities converge and the denser one sinks into the mantle beneath the other

• Convergent boundary

• A plate boundary where two tectonic plates slide horizontally past one another

• Transform boundary

• A plate boundary where two tectonic plates move apart from each other

• Divergent boundary

• A plate boundary where two tectonic plates move toward each other and collide
